“All probiotics are live microorganisms that, when provided in adequate amount,s provide a health benefit to the host, but mechanisms of action differ significantly by strain and organism.”
Probiotics are often grouped together, yet meaningful differences exist in how various organisms interact with the gastrointestinal environment. Strain specificity determines how stability, survival, and functional outcomes are achieved within pet food systems. Understanding these distinctions allows nutrition professionals to align product design with targeted health objectives. This perspective supports more precise formulation strategies that reflect both scientific evidence and manufacturing realities across pet food formats.
